1. Low Refrigerant Levels:

AC Not Working In Honda Civic

If the AC in your Honda Civic isn’t working, it could be due to low refrigerant levels caused by leaks in the system.

Refrigerant absorbs heat and moisture from the air inside your car, and without enough of it, your AC won’t cool the air properly.

To fix this, you’ll need to have your refrigerant levels checked and replaced if necessary. This can be done by a professional mechanic or yourself if you have the necessary tools and skills.

Refrigerant replacement is a straightforward process, but it requires proper handling and disposal of the old refrigerant.

It’s important to use the correct type of refrigerant for your Honda Civic because using the wrong type can damage your AC system and even pose a safety hazard.

Any leaks in your AC system should be fixed before adding new refrigerant, as the new refrigerant will simply leak out again.

If you suspect that your AC system has low refrigerant levels, it’s best to have it checked by a professional to ensure that the problem is properly diagnosed and fixed.

Remember, regular AC maintenance can prevent many AC issues, including low refrigerant levels.

2. Faulty Compressor:
